Unit 3 Review: Dilations and Similarity

Front

How do you determine if two triangles are similar?

Back

You can determine if two triangles are similar using the AA (Angle-Angle), SAS (Side-Angle-Side), or SSS (Side-Side-Side) similarity criteria.

Front

What does AA similarity mean?

Back

AA similarity means that if two angles of one triangle are equal to two angles of another triangle, then the triangles are similar.

Front

What does SAS similarity mean?

Back

SAS similarity means that if two sides of one triangle are in proportion to two sides of another triangle and the included angles are equal, then the triangles are similar.

Front

What does SSS similarity mean?

Back

SSS similarity means that if the corresponding sides of two triangles are in proportion, then the triangles are similar.

Front

What is the difference between congruent and similar figures?

Back

Congruent figures are identical in shape and size, while similar figures have the same shape but may differ in size.

Front

If two triangles are similar, what can be said about their corresponding angles?

Back

The corresponding angles of similar triangles are equal.

Front

If two triangles are similar, what can be said about their corresponding sides?

Back

The corresponding sides of similar triangles are in proportion.

Front

What is the SSS Congruence Postulate?

Back

The SSS Congruence Postulate states that if three sides of one triangle are equal to three sides of another triangle, then the triangles are congruent.

Front

What is the ASA Congruence Postulate?

Back

The ASA Congruence Postulate states that if two angles and the included side of one triangle are equal to two angles and the included side of another triangle, then the triangles are congruent.

Front

What is the AAS Congruence Postulate?

Back

The AAS Congruence Postulate states that if two angles and a non-included side of one triangle are equal to two angles and a non-included side of another triangle, then the triangles are congruent.
